release-5 restorecd issue

I'm not sure if this is fixed yet, sorry if it is.
I got the first version of the restore cd and did a complete overwrite
to a new drive on my Qube2 tonight.
When I tried to use chsh to change the shell, it complained that the
sticky bit wasn't set on /tmp.
I think this is common when unpacking the sets without using the
"preserve" option. If using tar, it's the -p option.
You can fix the problem by doing this:
chmod 1777 /tmp
Is this worth a pr?
